Problem getting on, primarily, the web (6)
I believe the answer is:
tissue
'web' is the definition.
(I've seen this in another clue)
'problem getting on primarily the' is the wordplay.
I cannot really see how this works, but
'problem' could be 'issue' (I've seen this before) and 'issue' is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tissue that I've seen before include "Paper hankie" , "cell block?" , "Cloth" , "Gauzy fabric" , "Thin fabric" .)
